Aortic Valve Repair for Severe Commissural Leaflet Defects Using Aortic Wall Patches

Area of Science:

• Cardiovascular Surgery
• Cardiac Valve Repair
• Aortic Valve Disease

Background:

• Annular dilatation and leaflet defects are common in aortic insufficiency, often requiring valve repair or replacement.
• Inadequate leaflet tissue during planned repair can unexpectedly necessitate prosthetic valve replacement.
• A need exists for effective repair methods for severe leaflet deficiencies in aortic valve insufficiency.

Purpose of the Study:

• To present a novel surgical technique for repairing severe aortic valve leaflet deficiencies.
• To evaluate the efficacy of using an autologous aortic wall patch for leaflet reconstruction.

Main Methods:

• A major leaflet defect in a patient with aortic insufficiency was reconstructed using an autologous aortic wall patch.
• The aortic wall strip was sutured to the valve annulus, with intima facing coaptation.
• Leaflet free-edge length was adjusted to match normal leaflets after geometric annuloplasty.

Main Results:

• A patient with grade 4 preoperative aortic insufficiency experienced a complete resolution of insufficiency after repair with an aortic wall patch.
• The patient demonstrated excellent echocardiographic parameters at 1 year postoperatively.
• This technique successfully addressed severe leaflet deficiency, avoiding prosthetic valve replacement.

Conclusions:

• Autologous aortic wall patches are an effective leaflet substitute for managing severe leaflet deficiencies during aortic valve repair.
• This technique provides a viable alternative to prosthetic valve replacement in complex aortic insufficiency cases.
• The presented method offers a stable and durable solution for aortic valve leaflet reconstruction.
